Identify the correct Lewis structure for the compound CH ₃- CH ₂- CH ₂- CHO .

Step-by-step solution

The given compound is CH ₃- CH ₂- CH ₂- CHO , which is an aldehyde (butanal). In an aldehyde, the functional group is - CHO , where the carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom ( -C(=O)H ). Looking at the given options: Option (A) shows an incorrect structure where hydrogen appears to form multiple bonds. Option (B) represents an ether ( CH ₃- CH ₂- CH ₂- O - CH ₃ ). Option (C) correctly shows a four-carbon chain with the terminal carbon double-bonded to an oxygen atom and
